AWD,RWD or FWD - Hyundai Performance Forums

Hey I was wondering which would be quicker, from 0-60km/hr[that's right, km/hr NOT mp/hr]?

I know with enough KW AWD would win, but what about for an X3 Excel? Stock probably isn't a whole lot of difference, but say one that is turbocharged, then couldn't traction become a problem if it was left as FWD?

ie, FWD is pulling, and RWD is pushing, but then of course, the FWD has the weight of the engine on the front wheels, wouldn't that help traction as opposed to the empty boot on the rear wheels?

Thanks,
Dizzo

how much HP/KW are we talking here?

And I'd say... AWD... get some killer tires, and you'll be set

for accel AWD the king but for top speed and handling RWD is the way....

the problem with FWD is that when you accelerate all the weight is transfer on the back wheel.... so you need really stiff spring on the back and you inflate tire to hi psi on the track to minimize that effect... RWD that an advantage to have all the weight on the back wheels because the power is over there....

you can achive bretty good 60Ft on the track butt offentrly with slick..... adn you need a LSD :hmmm:

Traction as been invent cause it's easier to drive on wet condition or winter.... it's really not a the best for Racing :hmmm:

Hey, say a stock X3 Excel, then with a stage two turbo kit from racingperformanceworks[RPW].

ohhhh ok. I understand alot better now. It's just like when you brake and the weight transfers to the front, hence drums at the back and the other ones[discs?] at the front.

]you can achive bretty good 60Ft on the track butt offentrly with slick..... adn you need a LSD

Whjat does LSD stand for? Something to do with a diff/driveline?

Well I just wanted to know what's the best setup for say 140kw at the flywheel, for a traffic light grand prix

ie from 0-60km/hr the fastest of awd, fwd or rwd.

fastest for Accel would be AWD.... ie 0-60km/h

but you can achive good thing with a FWD with nice tire light wheels a good supension....

the Hp or KW doesn't really is the problem you good have 70hp if you have shitty tire they will never stick to the road

a LSD is a limited slip Differencial it lock the wheels when one is sliping insted of letthing one slip and the other stick to the road.... so better acceleration

:

for the tire i don't really understand what you'R saying but yes compare to a FWD or RWD all 4 tire will wear but i thin it's pretty equal to FWD or RWD the will wear lest faster i'm pretty shure....

for the stage 2 turbo or thing like that... good start are decided on how well you know you'r car and how well you drive goodn tire are essancial it doesn'T matter if you have 500hp or 100hp you need those 3 things

FWD has more understeer than a RWD .
with the weight shifting to the back FWD will always lose traction more than a RWD unless TCS,SCS is involved.
RWD it will grip more than a FWD cause the weight is going to the rear tires.
Also it has much more oversteer than a FWD.
AWD it will understeer a little but in a straight line is the best cause all 4 wheels are gripping.

With a FWD car, if the normal ride height is slightly higher in the back than the front, you will get better times on the track than having a stiffer spring on the rear end and a leveled car.

Actually AWD has initiat understeer but once the AWD transfer weight to the proper wheels you get over steer. This is why AWD can be difficult to use in competition, its switches from one extrem to the other.

Just stay with fWD car was ment for it and its the safest of them all.

yea.. I mean.. do you realize the money you will be putting into this car if you start messing with the drivetrain layout.. Just for 'stoplight grand prix'?!

I have a 'grass roots motorsports' mag that tests this question. Although.. its not like they used the same car, with modified with each different drivetrain.. they used a BMW 325i or someting for RWD, both with and without traction control enabled.. An RSX type-S for the FWD, and a WRX for AWD. They were all stock completely stock cars. The basic results were.. every one has it's advantages and weaknesses, and which is best is highly dependant on ever situation.. and even the driver as well. So.. it's really up to each individual.

I'd say.. jsut stay with the FWD, and put all your money into making the FWD perform better. Otherwise.. you are going to spend money changing the the drivetrain (if you don't do it all yourself make that alot of money) and then, you're going to have to spend money to make that type of drivetrain handle better.

Swapping in a mitsu engine and AWD drivetrain would be one way for AWD though.. or maybe just the mitsu drivetrain somehow. Or, for RWD the best way to do it would be to move the engine to the rear and make it mid-engine, RWD. I have no clue how much fun you would have making a transverse-mounted front engine car into RWD.. heh

Fairly easy, but TIME CONSUMING.

You would have to modify the motor mounts, modify the firewall and floorboard for the driveline, Add structure between the subframe and body of the car to mount a tranny mount and redo the ass end for a live axle setup. The gas tank also would have to be moved to the back of the diff as well.
